Our verdict on each
G-Force
G-Force suits budget riders who want a throttle and a large battery without moving upmarket, with fat-tire, cargo, folding and step-through models listed at $599 to $1,899. The trade-off is partner-run servicing and a short frame warranty, so read the terms before buying.
Kingbull Bike
Kingbull Bike suits riders who want a throttle, a large battery and a low entry price without chasing a dealer network. Claimed range is 161 km, the largest battery in the range is 1,440 Wh, and repairs go through partner workshops rather than an in-house team.

Pros and cons
G-Force
Pros
- Throttle and removable battery as standard, with a 3,120 Wh pack on the ZM PRO and a claimed 338 km of range.
- Hydraulic disc brakes and a 181 kg payload rating make the RS useful for heavy loads and rough ground.
- A 14 days money-back window plus finance available, so a bike near $1,899 is easier to justify.
Cons
- Frame and battery cover runs 1 year and 1 year, thin for a bike listed at $1,899.
- Servicing is arranged through partner shops rather than company workshops, so check local coverage first.
- Belt drive is not offered, so the chain wants regular cleaning after wet or muddy rides.
Kingbull Bike
Pros
- A throttle comes as standard, so you can pull away from lights or a junction without winding the pedals hard.
- Frame and battery warranty both run 2 years, with a money back window of 15 days behind it.
- Payload reaches 181 kg on the hauling bike, and braking is hydraulic disc on the model these specs come from.
Cons
- Support runs on email, help centre and community only, so there is no phone line for a problem that happens away from a bench.
- Belt drive is not offered, so every bike comes with a chain to clean, oil and tension.
- Repairs go through partner workshops, so a fix depends on a third party rather than an in-house team.
Who each suits
G-Force
Who it suits
- Riders on a budget who want a throttle and a big pack, with the RS and ZM PRO line starting at $599.
- Anyone moving loads or riding rough ground, given fat tire, cargo and folding in the catalogue and a 181 kg payload rating on the RS.
- Buyers in the United States, CA and GB who want the choice of ordering direct or through a dealer.
Who should look elsewhere
- Anyone after a mountain bike: Kalkhoff lists city, hybrid and step through, and the G-Force range of fat tire, cargo and folding leaves e-MTBs out.
- Riders who want a city and commuter line rather than fat-tire and cargo machines: Tern covers cargo, commuter and folding.
- Buyers wanting fat-tire alongside commuter and e-MTB options from one maker: HK BEIRUI TRADE CO. lists commuter, folding and fat tire.
Kingbull Bike
Who it suits
- Riders in the US who want a throttle and fat tyres rather than a pedal-only commute bike.
- Long-distance riders, since 1,440 Wh of battery and 161 km of claimed range cover real gaps between charges.
- Buyers who would rather pay over time, since finance is available on a range starting at $899.
Who should look elsewhere
- Anyone set on a mid-drive e-MTB: Kalkhoff covers city, hybrid and step through, while the Kingbull motor sits in the hub (hub).
- Riders outside the US, or those who want a dealer-backed folding bike: Tern's cargo, commuter and folding sit in that territory, and Kingbull ships to US.

Questions about each
G-Force
How much does a G-Force e-bike cost?+
Prices run $599 to $1,899 across the range, and G-FORCE RS, G-FORCE RS ST, G-FORCE ZM PRO, G-FORCE DE-S are the reference bikes. That entry point puts G-Force at 32 of 149 brands on lowest price, while the top of the range sits at 48 of 145. Entry is competitive; the ceiling sits higher.
Which models does G-Force sell?+
The catalogue covers fat tire, cargo and folding, with G-FORCE RS, G-FORCE RS ST, G-FORCE ZM PRO, G-FORCE DE-S as the reference models. Motor setup is consistent across the line: hub drive from a bafang motor rated at 750 W, with a throttle on board. The RS and RS ST take heavy loads, the ZM PRO carries the biggest battery, and the DE-S is the step-through.
Kingbull Bike
What does a Kingbull Bike e-bike cost?+
Prices cover a wide band rather than a single figure. The cheapest bike in the line is $899 and the priciest is $1,499, so you pick a point in that range. The line-up runs from the Kingbull Hunter and Ranger through the Literider and Voyager models, so the budget you set decides which one comes home. Cover runs 2 years on frame and battery, which is the number to weigh against the price.
Is there a subscription or renewal fee after buying?+
There is no subscription involved, so nothing renews and there is no ongoing bill to plan for. What sits alongside the purchase price is cover: 2 years on the frame and 2 years on the battery, plus a money back window of 15 days. If you would rather spread the entry price of $899, finance is available.
